Answer:

C. 13 meters

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

$c^{2} = 12^{2} + 5^{2}$

12 x 12 = 144

5 x 5 = 25

$c^{2} = 144 + 25$

$c^{2} = 169$

$\sqrt{c^{2} } = \sqrt{169}$

c = $\sqrt{169}$

169 ÷ 13 = 13

1 $\sqrt{13 m}$

Please let me know if this helps!

Answer:

The correct line plot is choice C.

Step-by-step explanation:

If you look at the data values, you'll notice that there are three $11\frac{1}{4}$ , and the only line plot that depicts this is choice C, so that is the correct answer.

Determine whether each scale factor produces an expansion or a contraction under a dilation of the original image

blondinia [14]

Answer:

see the explanation

Step-by-step explanation:

we know that

If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image

If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image

Verify each value

1) -4

$\left|-4\right|=4$

$4> 1$

therefore

The dilation produces an expansion of the original image

2) 0.25

$\left|0.25\right|=0.25$

$0.25 < 1$

therefore

The dilation produces a contraction of the original image

3) -2/3

$\left|-2/3\right|=2/3$

$2/3 < 1$

therefore

The dilation produces a contraction of the original image

4) 2.3

$\left|2.3\right|=2.3$

$2.3 > 1$

therefore

The dilation produces an expansion of the original image

What are the domain and range of the function? f(x)=−3/5x^3

vichka [17]

f(x)= −3/5x³

The domain is all values x can be. There are no restrictions on x. it can be any real number (-∞ , ∞)

The range is all values y can be. There are noi restrictions on y either because the function is odd. y is (-∞ , ∞)

The best answer is D.
domain (-∞, 0] ∪[0, ∞)
range (-∞, 0] ∪[0, ∞)

What scale factor was used in the dilation ????? Helpppppp

slava [35]

Answer:

Step-by-step explanation:

Dilation = dividing original by (number) to = dilated version.

10/5=2

Dividing 10 by 5 to = 2

(10=original size) (2=dilated size)
